I absolutely loved my short stay at J no 14. The place is exactly as on the pictures: very welcoming, original and very clean. The rooms are comfortable and the house is located at the end of a quiet lane, within walking distance to the sky train. There is a 7 eleven just around the corner.
I didn't get to meet Pakasit but I met his wife who's lovely and cooked a delicious breakfast for me.
This a great place to stay in Bangkok and I will recommend it to anyone. In fact, I am coming back in two weeks time :)
